Almost three weeks later he stole a gold coin, a pair of shoes, a bag, a wallet, £30 and $800 from a property in Knightsbridge.

Speaking to the paper, Vidhur Mehra, director at Benham & Reeves Residential Lettings, said: ‘Ben Papantoniou was employed by us from August 8 2016 and his contract was terminated on March 23 2017 for reasons unrelated to his recent convictions.

‘We keep a tight control of our keys. Our understanding is that Ben fraudulently posed as an employee of Benham & Reeves Residential Lettings sometime after he had left our company.’

A spokesperson for Foxtons said the company was ‘sorry about the distress caused to the affected tenants’.

They added that the tenants were compensated for their losses.

In a statement, a spokesperson for Kinleigh, Folkard and Hayward said: ‘We have robust security systems in place for holding and releasing client keys. This was an isolated incident and as a result our procedures have been reinforced across our network of 60 branches.’

Giles Milner, marketing director of Chestertons, said they urge all agents, landlords and tenants to always remain vigilant.
